Kewell eager for Olympic Games chance
An elite team of 33 players is now in training on the New South Wales Central Coast in an attempt to secure spots in the Olyroos' final 18.
Three over-age players will be allowed in Australia's under-23 squad.
Olyroos assistant coach Ron Smith says many of the Socceroos have told him they are keen to play.
"Certainly Harry could well be in with a shout ... there has been a number (of interested players) but I won't mention any names," he said.
"A number of the senior players have said to (coach Graham Arnold) that look, you know, 'Consider me I'd be very interested', and I think that is a great sign.
"Graham has obviously spoken to one or two players to see of they are interested and so on and so far virtually everybody has said yes."
